I haven't done many critiques before...soo, I'll try my best! And please don't take anything too seriously ; ^ ;
First things first, this picture, is absolutely adorable! I love how you designed Pinkie Pie, as a human, the bright cheery colors and outfit design does an excellent job at portraying her upbeat, joyful personality! I love the coloring you've done, the soft shading is perfect and so smooth! The pose is also anatomically correct as well~ *I see you've improved^^!* The only thing that I think I can point out that is strange, is the rough slant of her left cheek? I think It pokes out too much? Other than that, everything looks great~!
I think the overall picture is very nice and delicate looking! You've definitely improved a lot on your Chibi anatomy. The shading on her dress is very nicely done too. You did a great job on how her hair flows back as well.
The only few things that look a little off to me would be the ribbon tied on her waist. I feel like that one loose ribbon strand coming down is just too straight down. Her left arm could probably have been a little bit longer too. (Not by much, but by like an inch?) It just feels a little bit too short compared to the other one. And her left foot seems a little awkward. I think it would look better if it was facing a bit more towards the audience.
Other than that, I really do like this Chibi! Everything is great, and you really have improved! The little designs on her dress is cute! Great job! ;u;
Negatives > First of all, I'm having trouble finding bad things about this. I will say though, that some more light tones would look good added to the hair and clothing. The hair and clothes seem to only have two tones - dark and the normal colour. I think the addition of some lighter tones would help add more depth to the image, especially on the hair. >The one cheek on the far side looks a little bit too pointed?
Positives > Well basically, she's absolutely adorable! > I really love the pose here -the movement in the arms and legs is brilliant and the hands look great too. Her expression is so adorable too with that cute smile and little wink. > The creases you've added in the clothes and shoes look perfect too! I love how accurate, yet neat they are.
